Wtf is this formation?

[Josip Crncic]

Can i beat him with 4-5-1V formation ?

I'm not experienced enough to advice you but what I've understood so far is that counter formations does not exist.
There's many factors which affect the match, like:
- your formation, which shouldn't be changed often, i would even say never
- players on their natural positions, their quality and how long do they play together
- orders, these affect the game huge I think
- players morale, condition, age..
- etc

Good luck
